I don't think an increase in sperm donor activity will necessarily make much of a dent. The growing demands of industrial society and the perceived diminishing value of having a family compared to life's other pleasures won't be so easily resolved through readily available sperm.

On that note though, perhaps relationships might be less common. Who knows, maybe we'll turn into bears.

Got a chuckle out of the Genghis Khan comparison. If I was an archer on a rampart, and I saw one of these guys on horseback dressed in Mongol armor, I'd probably laugh so hard that I'd fall right off the wall.
